HEATING AIVD VF'ENTILATING PLANT AND METHOD.

application mea ugust'aa, 192,7. `seran No. 214,482.

It is an .object of this invention to provide a method of heating the rooms of dwellings, or of the larger working spaces of stores, warehouses, factories or the like, which Con- 'i sists in returning the air4 from the heated space from the lower extremities ofthe room and from below Athe heated zone o the rom to an' air heater positioned in the room so that `there is a stratumor blanket of Vair above the working space' insulating it from the cold ceiling and thus reducing the area to be heated with an attending marked economy in fuel and absence of draughts along the floor. Other and further important objects of this invention will be apparentfrom the disclosures in the specification and the accompanying drawings. l

This invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings: Figure 1 shows a room in elevation with a heater of the unit type Upositioned in the centre of the room and a suggested arrangement of air conduits in the floor section.

Figure 2 is a'plan view of the above.- As shown in the drawings: rEhe-numeral 10 indicates a heater of the unit type positioned onsthe floor 17 of the roonr-and midway between thewalls 16 of the room.

Heated air is expelled from the heater througl'i the lateral openings as indicated at 15, Figure I.. In a suggested arrangement, the air falling throu h the space to be heated enters av conduit 12 orm'ed in the Hoor 17 of the room through an aperture 13 where an upturned end of the conduit 12 registers therein, and is carried -along the conduit 12 to 40 emerge through another upturned end 14 which registers in an opening in the floor and within the body of the heater 10.

While the conduit 12-is shown within the floor in Figure 1, it may well be supported be- "i5 low the floor, or consist of a slot formed in the floorwitha cover at floor level without in-y terfering with its purpose, namely, to enable the air to be returned to the heater without .to travel from the vdischarge openings on the the presencel of objectionable draughts movmg from the walls of the room along the floor and towards the heater and to maintain an undisturbed blanket of insulating air above the working space.

, In heating systems employing the unit type "of, heater positioned on the floor of the room the air is expelled laterally so that the blanket or stratum of relatively cold air above the turbulent zone adjacent to the air discharg-l lng openings may remain relatively quiet. This is highly desirable, for this layer insulates the ceiling and reduces the space to be heated by an appreciable amount. lThe method of the applicant compels the heated air heater outwardly" and downwardly towards 'the walls as indicated at 19in Figure 1 and decreasesits tendency to sweep away the insulating layer. In other words, the turbulent zone adjacentthe discharge openings is bent downwardly. A

I am awaie that many changes may bey l made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not pur ose limiting the patent anted hereon, ot erwise ythan necessitated y the prior art.

I claim as my'invention:

A heating arrangement for rooms and like spaces having enclosingwalls, consisting of a heater disposed therein substantially remote' from said walls and having heated 4air outlets discharging laterally therefromtowards the walls of the room and below the top thereof, and air-return conduits opening at their inner ends into the lower portion of4 the heater,y said conduits'having outer intake ends near the said walls and the lower extremities thereof, j whereby to avoid draughts along the floor of the room, and to maintain a.- relatively quiescent stratum' of air above the heated zone.' l

In testimony whereof I have hereunto subscribed my name at Chicago, Cook'County, Illinois.
